EALLOW protection enables write access to emulation and other protected registers. The CPU can set this bit using EALLOW instruction and clear this bit using EDIS instruction. The protection can be used to prevent data being written to the wrong place, which can result from conditions like boundary exceeding, incorrect pointers, stack overflow or corruption, and so forth. Reads from the protected registers are always allowed. TI recommends issuing an EDIS for protection once the write of protected registers are complete.
